Cisco ePDG Evolved Packet Data Gateway

Hierarchical Navigation

Strong, Highly Secure Support for Mobile Networks

Cisco Evolved Packet Data Gateway (ePDG) is critical to the network function of the 4G mobile core network, known as the evolved packet core (EPC). The ePDG is responsible for interworking between the EPC and untrusted non-3GPP networks that require secure access, such as a WiFi, LTE metro, and femtocell access networks. The ePDG function is supported by the industry-leading Cisco ASR 5000 Series and provides:

High throughput

High call transaction rates

Industry leading IPSec tunnels terminated

Rapid packet processing

Significant memory resources

Security for Mobile Roaming, and More

The ePDG can use either IPSec/IKEv2 or proxy mobile IPv6 (in case the mobile subscriber is roaming in an untrusted non-3GPP system) for highly secure access to the EPC network. The ePDG builds strength and security into the network using:

Tunnel authentication and authorization

Transport level packet marking in the uplink

Policy enforcement of Quality of Service (QoS) based on information received via Authorization, Authentication, Accounting (AAA)
